in the libc rpc code.  The main difference between this and the previous
version is the use of a simple free list that simplifies the logic when
adding a socket to svc_pollfd.  I've also added code to pack svc_pollfd
when the free list gets too big.  The idea general idea is to keep
svc_pollfd as tightly packed as possible to make poll(2) efficient.

code that assign a u_int value to x_handy.  However, this means
that we need to be careful checking for overflow as we can no longer
subtract a value and check the result for < 0.  We reorder the
expression instead to avoid this problem (basic algebra).

entire trees for testing anyway, I might as well do this intrusive touching
of include files now.  Added openBSD tags.

not rpc-specific and other stuff uses it now.
